This is really well done piece. While on the outset the concept seems very simple, I can see that it's quite a complex depiction and really a love letter to the entire city when you make one of these, considering the level of detail you've gone into. Your color palette is the highlight of the entire series. They've got the worn out map feel as well as a very pop music vibe to them, sort of like record label covers, adding to their nostalgic appeal. Well done!
